CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the priority to the Chinese Patent Application No. 202010129824.4, filed on Feb. 28, 2020, the disclosure of which is incorporated therein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the field of deep learning, and in particular to a text labeling method and device.

BACKGROUND

In many speech recognition application scenarios, a result of speech recognition usually does not contain any punctuation marks. The text of the recognition result obtained in this way has no pause. If such a text without pauses is directly delivered to a downstream task, execution quality of the downstream task will be deteriorated because the downstream task is sensitive to pauses and punctuations. Therefore, the overall processing quality of the system can be improved by adding punctuations to the text of the speech recognition result.

For example, in the scene of a translation machine, a sentence spoken by the user is recognized by Automatic Speech Recognition (ASR for short) as “he bought a new car a plate number of which is Hu B96R11.” This recognition result has a problem that there is no pause between the character “car” and “a plate number.” The correct recognition result should be “he bought a new car, a plate number of which is Hu B96R11.” However, only an unpunctuated recognition result is obtained because the ASR is provided with only the user's speech and does not have a function of making pauses. Due to the lack of punctuations, the meaning of the recognition result is not clear.

Such result displayed on the screen of the translation machine will affect the user experience. Further, if the unpunctuated speech recognition result is input into a translation model, the translation in a translation task may be inaccurate, because sentences without punctuations can cause ambiguity. Therefore, it is meaningful and important to punctuate the unpunctuated text.

Common punctuation prediction methods generally include the followings:

1. performing feature extraction on a sequence based on recurrent neural network (RNN) and performing punctuation prediction; and

2. performing feature extraction on a sequence based on a self-attention mechanism and performing punctuation prediction.

The method based on a recurrent neural network has the problem that the speed of feature extraction is slow and the speech input may be forgotten. This is because the recurrent neural network has a dependency in the time sequence. In other words, the result of the next moment depends on the output of the previous moment, causing the speed of feature extraction to be slow if the length of speech is long. Besides, due to the problem of the model, the speech input may be forgotten if the length of the speech is long.

Although the method based on the self-attention mechanism has no dependency in the time sequence, features thereof at each moment are obtained by weighting all context information, so that the efficiency is low if the input text is very long. Moreover, since whether to add punctuations is determined based on all context information, the accuracy of the determination will be affected if there is a large amount of context information. This can result in a low accuracy in a process of punctuating a long text.

DETAILED DESCRIPTION

Exemplary embodiments will be described in detail herein, examples of which are shown in the drawings. When referring to the drawings below, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices and methods consistent with some aspects of the disclosure as detailed in the appended claims.

No matter the mechanism based on recurrent neural network or the mechanism based on self-attention is adopted, low efficiency and low accuracy are prone to occur in the process of feature extraction and punctuation prediction.

In view of the above matter, embodiments of the present disclosure provide a text labeling method and device that extract features through dynamic convolution feature extraction and insert labels based on the feature extraction, thereby solving the problem of low efficiency and low accuracy of the feature extraction process, improving the user experience, and improving the accuracy of downstream tasks of the speech recognition business.

An exemplary embodiment of the present disclosure provides a text labeling method. A process of labeling text using this method is shown in FIG. 1 and includes the following steps.

In step 101, input information is processed to obtain word embedding representation information of the input information. In this step, the input information is a text obtained through the speech recognition, and is input to a training stage model, so as to start the text labeling process. After a preliminary processing is made on the input information, the input information is divided into characters, and corresponding word embedding representation information is obtained.

In step 102, dynamic convolution feature extraction is performed on the word embedding representation information to obtain a classification result of each character from the word embedding representation information. In this step, a dynamic convolution feature extractor is used to perform feature processing on the word embedding representation information to obtain the classification result of each character from the word embedding information. Specifically, the classification result is a calculation result of a normalized exponential function/softmax function. Based on the classification result of each character, it is possible to determine the punctuation information to be labeled behind each character.

In step 103, a label is inserted into the input information based on the classification result. In this step, the punctuation to be labeled behind each character is determined based on the classification result of each character, and an accurate speech recognition result text is obtained after the label is inserted.

An exemplary embodiment of the present disclosure further provides a text labeling method. The process of text labeling using this method is shown in FIG. 2 and includes the following steps.

In step 201, training samples are collected and used to perform training to obtain a training stage model. In this step, a large amount of punctuated text can be collected through web crawling and other means, and the text can be processed into parallel corpus of data sequence without punctuations and result sequence with punctuation to form a training corpus. The source end of the training corpus is a sequence without punctuations, and the target end is the type of punctuation added behind each character. The type of punctuation includes non-punctuation, period, comma, question mark and other punctuation types, which are denoted by “N”, “°”, “,” and “?” respectively. Exemplarily, in the case that a Chinese text is punctuated automatically, a process of preprocessing training data to obtain training samples is shown in Table 1. First, in step, the original text is segmented to split the text of a sentence into characters, and these characters are separated with spaces. Second, in step2, on the basis of step1, the punctuation type predicted for each character is obtained according to whether a punctuation mark is behind the input character, and thus a parallel corpus for training is obtained, that is, a training sample.

TABLE 1  Inputs: “ 

 ,  

 ?”  Step 1:  

 ,  

 ?  Step 2: “ 

   

 ” --- “N N N N N N N, N N N N N?”  Outputs: source = “ 

   

 ”, target = “N N N N N N N, N N N N N?”

Then, the training samples are input into the model for training, and the training stage model is generated.

In step 202, dynamic convolution feature extraction is performed on the word embedding representation information to obtain the classification result of each character from the word embedding representation information.

The overall architecture of the training stage model used in the embodiments of the present disclosure is shown in FIG. 3, and includes an input layer, a word indicator layer, a word embedding layer, a dynamic convolution layer, and a punctuation result layer. Through the training stage model, the data with punctuations is processed into a source end without punctuations and a target end representing the result of punctuation classification.

At the input layer, the input information is split into individual characters. At the word indicator layer, each character at the source end is converted into an ID (unique identifier) in a predefined word list based on the word list. At the word embedding layer, the word embedding representation corresponding to each character is obtained based on the ID of each character.

This step is shown in FIG. 4 and includes the following steps.

In step 401, each character in the input information is converted into a unique word indicator of the character. Specifically, a unique word indicator of each character in the input information, such as the ID in the predefined word list, is obtained through the above conversion.

In step 402, a word embedding layer processing is performed on the word indicator to obtain a word embedding representation corresponding to each word indicator, and form word embedding representation information of the input information. Specifically, at the word embedding layer, the word embedding representation corresponding to each character is obtained based on the ID of each character.

In step 203, dynamic convolution feature extraction is performed on the word embedding representation information to obtain the classification result of each character from the word embedding representation information.

This step is shown in FIG. 5 and includes the following steps.

In step 501, the word embedding layer information in a time window corresponding to each character is used as context information for feature extraction. In this step, in the dynamic convolution layer, the word embedding representation information is input into the dynamic convolution feature extractor, and the word embedding layer information in the time window corresponding to each character is used as the context information for feature extraction.

In step 502, dynamic convolution feature extraction is performed on the context information to obtain a classification result of each character from the word embedding representation information. In this step, the feature extraction is performed by the dynamic convolution feature extractor to obtain the classification result of each character. Specifically, the softmax classification of the features is performed using a fully connected layer to obtain the classification result of each character, that is, the classification result about the type of the punctuation behind each character.

The feature extraction method of the dynamic convolution feature extractor is different from the feature extraction method of the feature extractor based on self-attention mechanism. The feature extraction method of the feature extractor based on the self-attention mechanism uses the input at all times as the context information for feature extraction, as shown in FIG. 6. The feature extractor based on dynamic convolution only uses the input in the window at current time as the context information for feature extraction, as shown in FIG. 7, which has advantages in automatically adding labels to the text, especially in the task of adding punctuations. This is because that when determining whether a punctuation is needed behind a character in the text, only the information of the character near this character is needed, and the model does not need to know the entire input information. As for the feature extraction method based on self-attention, the feature at each moment is obtained from the input at all moments of the previous layer. On the contrary, the output of the feature extractor based on the dynamic convolution for each character/time is only obtained based on the input within a corresponding time window in the previous layer.

Further, dynamic convolution is also different from the traditional convolution feature extractor. The dynamic convolution feature extractor has a different convolution kernel at each time, and the convolution kernel is obtained according to the input at the current time. The traditional convolution feature extractor has the same convolution kernel at each moment. Since the convolution operation is used, the parallelism of the algorithm is relatively high, so the model is much faster than the feature extractor based on the recurrent neural network and the feature extractor based on the self-attention mechanism.

In step 204, a label is inserted into the input information based on the classification result.

This step is shown in FIG. 8 and includes the following steps.

In step 801, punctuation information behind each character is determined based on the classification result of each character. In this step, based on the classification result of each character, that is, the classification result of the punctuation that can be added/inserted behind each character, the punctuation information behind each character is determined.

In step 802, the punctuation information is inserted behind the corresponding character in the input information. In this step, the punctuation information is inserted behind the character to obtain the final accurate speech recognition result with punctuations. The speech recognition result with punctuations can be directly output to the user as a processing result, and can also be provided to other downstream services. The downstream service performs tasks based on this speech recognition result, thus improving the accuracy.
